The Burmese opposition leader Aung San Suu Kyi will be given the rare honour of addressing both Houses of Parliament later on Thursday.

She will deliver her speech in Westminster Hall, an honour normally only accorded to heads of state.

It is her first trip to Britain since leaving 24 years ago to lead Burma's pro-democracy movement.

Ms Suu Kyi will also meet the Prince of Wales and the Duchess of Cornwall and hold talks with the prime minister.

She met David Cameron in April when he became the first Western leader to visit Burma after the country's military leaders decided to allow her and her party to stand in parliamentary elections.

Since then, he has championed the suspension of international sanctions against Burma arguing that new President Thein Sein is genuinely committed to reform.

However, Foreign Secretary William Hague - who will hold his own talks with Ms Suu Kyi - cautioned in the Commons on Wednesday that there was "still a long way to go" to bring democracy to Burma and end ethnic conflicts.
